The other soldiers who died at Deepcut barracks were Pte Sean Benton, who was found with five bullet wounds to his chest in June 1995, and Pte James Collinson from a single gunshot wound in March 2002.

A spokesman for Surrey Police said: “In April 2014, Surrey Police received a request from counsel representing the family of Private Geoff Gray, who died at Princess Royal Barracks, Deepcut, in 2001, to disclose all material relating to the investigation into his death.

“The force agreed to this request on a voluntary basis and is in the process of disclosing documents relating to Private Gray.

“Surrey Police also received similar requests for disclosure from representatives of the families of Private Cheryl James, Private Sean Benton and Private James Collinson, who died at the Princess Royal Barracks, Deepcut, between 1995 and 2002.

“The force has as a dedicated team to complete disclosure as quickly and effectively as possible to meet the families’ requests and prepare for any High Court hearings or possible new inquests in the future.”

Assistant Chief Constable Stuart Cundy added: “Our thoughts remain with the families of all four young soldiers who died at the Princess Royal Barracks between 1995 and 2002.

"Surrey Police is not re-investigating the deaths, but is committed to providing disclosure to the families through their legal teams and will provide the appropriate support for any potential inquests in the future."
